A structure, box or hopper for transportation is shown, which instead of bei ng totally manufactured and made up of steel - whichever its technical features or thickness - is built on the basis of a mixed structure of polymers and steels. In this way, polymers themselves are the body of the hopper on the one hand, with these polymers being the portion where load is transported and, therefore, bearing the impact and wea r and tear requirements caused by the material transported, and becoming incorporated t o the hopper's steel element through different systems of fastening, adjustment an d suspension and, on the other hand, the metal structure fulfills an unknown function in hoppers, that is, becoming a fastening and supporting element for the polymeric component and not becoming a material-carrying surface or shield against impacts and wear of t he same. |
